Code 56? - ZR-1 Net Registry Forums

Update:

The Vacuum sensor was reading almost 5Vs. Somehow the port throttle vacuum soleniod, the one that controls the secondary flaps was staying open allowing the secondaries to be open all the time.

Tore the plenum down, all vacuum lines are as they should be. Tested them all. Reseated the connector on the solenoid, and then tested the vacuum sensor with my multimeter, would still read high.

Tapped the solenoid with my screw driver, released vacuum from the secondaries, and tried again, and everything works. Brand new solenoid stuck open the first time it was used.

All is well now, for the time being....
